I do know Vit-C.has been recommended for years to help prevent colds thru the winter months, that works for me. I truly haven't had a cold in 25 years or more. But I take a host of vitamins because of my low immune scale.
But I have taken vitamin C and Zink to prevent colds. I don't know if it helps with my p/s/a or r/a but I don't think it can hurt.
